Convert TopoJSON to SHP
Turn TopoJSON into Shapefile (zipped) instantly in your browser. No upload, no account, and no file ever crosses the network.
About TopoJSON
Quantized topology used by D3 and web cartography.
- Export quantizes coordinates and writes one arc per ring; arcs are not deduplicated.
About Shapefile (zipped)
Real .shp/.shx/.dbf/.prj/.cpg written in the browser, packaged as a ZIP.
- Field names are truncated to 10 characters and text values to 254 bytes (DBF limits).
- Mixed geometry types are split into one shapefile layer per type.
Step by step
How to convert TopoJSON to SHP
- 01
Drop your .topojson file
Open the converter and drop the TopoJSON file — parsing happens locally in a Web Worker, so nothing is uploaded.
- 02
Choose SHP as the output
Pick SHP, reproject to any of 180+ coordinate systems if needed, trim attributes and preview the geometry on a map.
- 03
Download the .zip file
Save a single file, or convert a whole batch and download everything as a ZIP. Nothing is stored after the download.
TopoJSON to SHP — questions
Is converting TopoJSON to SHP really private?
Yes. The conversion runs entirely in your browser using a Web Worker — the TopoJSON file is never sent to a server, so it works with confidential data and offline.
Do I need an account to convert TopoJSON to SHP?
No. There is no signup, no email and no install. Open the converter, drop the file and download the result.
What happens to attributes and coordinate systems?
Field names are truncated to 10 characters and text values to 254 bytes (DBF limits). You can also reproject between 180+ coordinate reference systems or add a custom proj4 definition before writing.
